Recently I have switched to use VSCode IDE for Ruby and Elixir development.

And as I like to use Material Theme in editors (initially inspired by Sublimes Material theme), the same exist for VSCode. But not all panels are colored in Material colors (due to previous VSCode API limitations), and vscode-custom-theme extension helped with this (but now there is no need in it).

Trailblazer is a high-level Architecture libraries for the Ruby web application (not only for Rails). If you are no familiar with it yet - take a 20 minutes walk through guide...

I want to cover once again those places where our team had issues or misunderstanding. Trailblazer documentation got a lot of improvements recently and keep getting more and more care. Some points from this list are covered by the docs, but in practice not everything was smooth.

Recently I have evaluated different HTTP request wrapper libraries for Ruby project.
Took 3 most popular: Faraday, RestClient, HTTParty. And found an interesting fact that illustrates very common issue in the world of Ruby libs.

Metaprogramming is used for the sake of Metaprogramming - "because it is Ruby and I can do it like this...". Not to make end-user developer life simpler.

Let's see the main purpose of HTTP request lib - is to send HTTP request (GET, POST, etc.). And the main purpose should dictate public interface of the lib classes. It should have a generic method to do any kind of HTTP request + shortcut methods to do the most common requests, like GET and POST.

That is what all these libs have

# kind-a this
connection.get(url)
# or this
Client.post(url, body_params_hash)
# it doesn't really matter is it static or object method

The issue is - these methods get/post are not real. For some reasons lib author try to spare 10 lines of code, but to use "cool Metaprogramming approach".
The consequences of this - I am as an end-user of this lib, can't Ctrl+Click on post method in my IDE to see how it is implemented and what's happen inside. Because this method does not really exist in class, it appears in runtime after class_eval or define_method. I can't even find the place in Gem where it defined without getting deep in internal implementation.
That is a bit frustrating for me. These 3-5 methods are the most important parts of such a lib, I don't care about all other parts, but exactly these parts are hidden from me. And for what good reason?

As we can see it is 3-5 line methods. There is no any problem to write them explicitly and hardcode method name inside them + extract all repeating lines inside a separate method. That is absolutely normal code design approach. Instead of sacrificing code simplicity and readability of favor of code size.

With Linux having ssh key in .ssh folder and configuring ~/.ssh/configis enough.
But on MacOS I get an error during Git clone (and Capistrano deploy) like this:

git clone git@github-pewpew:.../...git
Cloning into 'MyRepo'...
ERROR: Repository not found.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.

a bit confusing, but an error is not with Repo by itself (if you are completely sure that you are the repo owner or have write-rights).

Solution

On MacOS X I need to additional keys manually by

$ ssh-add ~/.ssh/id_rsa_pewpew

and you can check what key are in use right now

$ ssh-add -l

Note

On MacOS X you will need to add key after every system restart.
It looks like we need to use OSX Keychain to reload them authomatically via
